Red Dead Redemption -- Undead Nightmare Walkthrough & Strategy Guide

Once you save Riverview, you can find McKenna in the tents on the south side of town, and he's looking to make a new movie. He wants you to bring him a hogtied Retcher so he can make motion picture history.

There's no real reward for this mission, except that it's a requirement for unlocking the Undead Hunter outfit. In order to successfully hogtie a Retcher and bring it back to McKenna, you have to run into one as part of a random encounter. If you try to grab a Retcher from a predetermined encounter, like Gaptooth Breach, it'll explode on its own the moment the town's saved. You also can't fast-travel with a hogtied undead; the undead will simply not be on your horse when you arrive at your destination.

The best place to find a Retcher in New Austin is on the cliffs north of Tumbleweed, mostly because an encountered Retcher will only have a couple of normal undead or Bolters with it. There are always a few in Jorge's Gap, which is a twenty-four-seven zombie mosh pit, but the sheer volume of undead in there is a complicating factor.

To complete the mission, simply bring the Retcher to McKenna, then relax in the warm glow of schadenfreude.
